The config files for Dovecot should be pretty platform independent across linux distros I'd imagine. What errors were you getting?

Wish I could be of more help as far as finding a Dovecot 1.x package but I have no experience with CentOS/yum.

Hope you get things working.

Hi @Jerzzp,

First it was around the lower part of the namespace block

namespace {
inbox = yes
location =
prefix = INBOX.
separator = .
type = private
}

a delimiter was being expected. I think it was the "." after "separator"

when I got past that, then there was another issue:
ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem

it was something about the URLs not being correct/files did not exist.
I eventually had to get some help.

It is working fine now.
Thanks a whole lot.

How do you now create virtual mailbox users?
from the command line?

Been searching for a visual tool, then I ran into Postfix Admin.. but Postfix admin has its own database for managing virtual domains/user mailboxes and you're supposed to configure Postfix to work with that..

but I have already created a database in MySQL for that....

How did you get around this problem?

Well I'd just get a tool for MySQL. I use phpMyAdmin.

I used the built-in tool to convert my config files. Things are working pretty well.

doveconf -n -c dovecot.conf-centos5 > dovecot.conf

/etc/dovecot/dovecot.conf (notice the directory structure change).
